Practicality makes a comeback: Dynamic MRI without the overhead

Introduction: Free-breathing, non-gated time-resolved scans carry great potential for applications such as cardiac imaging, catheter tracking and image guided therapy. However, insufficient temporal resolution and problems with real-time reconstruction have limited their use. The sliding window algorithm solves the second problem, but is known to introduce temporal blurring. Modern approaches s...

Nothing in Biology makes Sense without the Flavour of Mathematics

The elements of mathematical language are on the whole precise and unambigous. In the history of science, one can see that the development of any branch of science begins from the largely descriptive, goes on to become explanatory at the qualitative level, and finally becomes explanatory at the quantitative level. With the application of mathematical principles, physics made the transition from...

Learning To Do Without Cognitiony

In this paper we show that a phenomenon in animal learning theory (the outcome devaluation eeect) for which there is dispute over whether explicit representations and symbolic reasoning is required for its performance , does not require such things. This is done using a reactive motivational model, previously inspired from ethological thought, to which some simple reinforcement learning rules a...
